. IMPROVEMENT IN HORSESHCOEI-NAIL MACH|NES..

. Specification forming part of Letters Patent No. 196,585, datedOctober 30, 1877; application filed August 21, 1877.

To all whom it may concern:

Be it known that I, WILLIAM KnYs, of the city of Montreal, of theProvince of Quebec, of the Dominion of Canada, have invented a new anduseful Machine for Making Horseshoe-Nails; and do hereby declare thesame to be described in the following specification and represented inthe accompanying drawings, of which Figure 1 is a top view, and Figs. 2and 3 opposite side elevations, of it. Fig. 4 is a vertical sectiontaken through the dies and rolls for forming, tapering, and pointing theblank, as will be hereinafter described. Fig. 5 is a top view of therecessed swaging roll. Figs. 6 and -7 are views of the female dies, andFigs. 8 and 9 are end views of the male dies, used in such machine.

With the said machine a nail-blank is first punched from a thin metallicplate, and falls into a spout, by which it is conducted to the bite of apair ofswaging-rolls, by whose action it is swaged and tapered inthickness. From the said rolls it passes into another conduit, throughwhich it falls down to and in front of the female shaping and pointingdie, through which and from the machine it is next forced by the fellowor male die, and by the two is finished in shape and has its pointcompleted.

My invention consists in the machine or combination, substantially ashereinafter explained, consisting of blank -forming dies, swaging-rolls, spouts or conductors, an adjustable shoulder or shelf, andfinishing-dies, arranged and provided with operative mechanism, as setforth.

- In the drawings, A denotes the frame of the machine. Within an arm, B,extending up from such frame there is placed in a socket, a, in the saidarm the female die Gr for forming the blank, such die being chambered,as shown at b. The chamber opens into a short spout, C, leading to thebite of two rolls,D E. These rolls are fixed on separate shafts c d,arranged in suitable bearings in the frame A. The roll D is recessed, asrepresented at e, to receive the blank, and, with the roll E, to taperit and reduce it properly in thickness, and bevel it while it may bepassing between them, (the 9, leading through the projection h, by whichthe die is supported.

The male dies or punches for the two female dies G H are shown at L andM as projecting from the ends of two slides or carriers, 1" s. The tworoll-shafts c d have fixed upon them two connecting-gears, h i, therebeing also on one of such shafts a driving-gear, k, which engages with atransmittinggear, I, that, in turn, engages with another gear, m, fixedon the main driving-shaft K of the machine, all being arranged asrepresented. The said gear also engages with two other gears, 12 0,fixed on separate shafts p q, provided with mechanism for imparting tothe two male-die carriers 1 8 their reciprocating rectilinear motions.Such mechanism for one of such shafts is a crank-wheel, t, and aconnecting-rod, 'u, the latter being pivoted to the carrier 8 and to thewrist of the crank-wheel.

For actuating the upper die-carrier r, it has a straight slot, o, madethrough it transversely. In this slot is a slide, w, provided with acylindrical hole, as, to receive the wrist of a crank, y, fixed on theshaft 19. During each revolution of the said shaft the die-carrier willbe advanced and retracted. At the upper end of the spout C there is aprojection, Z, upon which the lower edge of the nail-plate rests whilebeing punched by the die L. The main shaft K is furnished with adriving-wheel, M, to receive a belt from some proper motor. On the saidwheel being revolved, the various movable members of the machine will beput in motion. The nail-plate will have a nailblank punched from it andforced through the upper female die into the chamber thereof, from whichsuch blank will fall into the short spout C, and by it be conducted toand between the swaging-rolls. These latter will seize the blank andreduce or taper it in its thickness. From the said rolls the blank willfall into and through the conductor F, to and between the lower dies, bywhich it will next be finished, or have its surplus metal removed fromit.

I do not claim a machine made as shown in the United States Patent No.190,011, which in some respects, is analogous to that herein eforeexplained, though difl'ering in various essential particulars, mymachine being much simpler and difl'erent in construction, and operatingin a diflerent manner to make a nail.

I have no presser to hold in a die the nailblank by its head; nor have Iany clearer, funnel-shaped guide, spring-fork fingers, or various otherdevices which are essential to the said machine. In my machine thenail-blank, after being severed from the plate by the dies G L, dropsinto an inclined spout, C, and thence between the swaging-rolls, afterwhich it passes between such rolls, and thence into WM. KEYS.
